sorry i havent been able to get any help from mustang communities. im putting a wet kit + window switch on an 04 mach1 and i got some questions-

THANKS FOR THE HELP IN ADVANCE!

need to know what wires to tap to get the rpm for the window switch.

also what wire can i tap under the dash to get the 12volt key'd ignition.

and also whats the best way to run wires through the fire wall.

 

I dont know but if you run a aftermarket tach on the newer mod motors you have to run a tach driver that maybe something to look into

 

u can use a wire off one of the coils or get a tach driver.
we got the signal from a coil wire and ran the wires through the boot where the harrness is.
